Java怎樣實現俄羅斯方塊小游戲源碼

這篇文章主要為大家分析了Java怎樣實現俄羅斯方塊小游戲源碼的相關知識點，內容詳細易懂，操作細節合理，具有一定參考價值。如果感興趣的話，不妨跟著跟隨小編一起來看看，下面跟著小編一起深入學習“Java怎樣實現俄羅斯方塊小游戲源碼”的知識吧。

一、最終效果

二、功能需求

1、 在二維平面里面用各種隨機產生的方塊堆積木，每滿一行消去一行，當達到頂部時，游戲結束。
2、 通過方向鍵來控制方塊轉動，左移，右移和直落。
3、 方塊下落統一設置藍色，接觸底部變粉色。
4、 計算分數，分數是由方塊的類型決定的，每堆積一個方塊就把分數累加到總分中。
5、 游戲有開始、重新開始、降低提高級數（速度）、暫停、退出

三、程序實現

這個是最基礎的方塊素材
